2014 Chevrolet Silverado 1500 Engine

Ignition lock actuator faulty. Causing ingition to be stuck in start position.

The air conditioner condenser has a small leak causing the refrigerant to leak out. This is a known problem with all gm Silverado 2014-2017 and a recall needs to be issued. They are all leaking in the same place due to a faulty weld from the factory.

the truck went in for the fuel injector number 6 again. went in on June 13 and on the 12 as well. on the 12 they said it was the number 6 coil. they then gave it back but the next day had to be returned again for the same problem. this time they found the number 6 fuel injector was possibly shorted out. the service manager did call and said that i was right that it was the fuel injector. i feel that i paid for a coil that should not have been replaced in the first place.

I was driving home from work on 5/9/2025 and my truck slowly started to loose power and I almost got rear ended going up a hill. NO check engine lights or symptoms noted prior I was able to make it to the Chevy Dealer here in town where i Live and dropped off. dealer noted cyl 4 has a misfireand there is a tick noise on that bank.checked and found no compression on cyl 4, removed valve cover and found that the lifter for cyl 4 is broken and pushrod bent. After reasearching found this to be a common problem, contacted Chevy reagarding this as truck is low miles (88k) NO help offered.

While driving to work a month ago (3/19/25) I lost the power to accelerate out of nowhere. And my truck started making this noise, what I can only describe as a winding up noise while trying to accelerate. I was going 55mph on a busy morning commute. There were no warning lights. I pulled over and shut the truck off. Checked oil (even though it was changed a week or 2 prior). Oil was fine. Let truck sit for 10 mins then tried to turn back on, it started but had that winding up noise when just sitting in idle, the check engine light then came on after it was on for a minute or so. Ran codes at home, and truck started making an additional rattle noise on top of the winding up noise when had to be turned on. One code was the crankshaft position sensor, we changed that out. Then the truck wouldn't start. Taken to Dealership, and they said initially they found a broken connector to the engine harness. Fixed that then truck started but still making the rattle/clunk type noise and louder than at home so they continued diagnostics because they said the noise sounds like a rod knock, so rod either being bent/broken/slipping. Further diagnostics found that oil and coolant are mixed along with metal shavings through engine so new engine is needed.

Lifter failure happened while traveling home from Florida to SC. I was towing a vehicle and barely made it home. Having to drive at low speeds on the interstate put me at risk for accident. Now that I’m home I’m losing money because I have been unable to work due to not being able to drive the truck. The dealership quoted me $4700 to fix when there is a known class action lawsuit for this exact problem. GM should just replace these motors. This is very dangerous. There were no prior warning signs it just started ticking after stopping for fuel.

Faulty Active Fuel Management Lifter, Cylinder 6 Misfire causes engine to suddenly lose power. Mechanic has replaced faulty Lifter twice within a couple weeks and same issue keeps occurring.

Automatic fuel management system failure has caused a p0300 code as multiple misfire diagnosed to cylinder 4 dead with no compression. This vehicle is no longer drivable and I still owe $21,000. GM knows of this failure for a long time. At current I have no way to pay for repairs and making payments on a truck I can not drive. I bought this vehicle used at 83,000 miles and have put 16,000 miles on it in 2 1/2 years

I have a 2014 Chevrolet Silverado 4x4 which the "O2 Sensors" are going out and causes my truck to run rich and lose horsepower. My truck does burn more fumes from the exhaust causing bad pollution in the air. Can type of action this be considered as a recall.

Transmission Light comes on to say cut engine off, if not done quickly, just dies. It can cut off at any time. I just purchased truck and took it to the chevrolet dealer they told me this year make and model has had a lot of transmission issues that the torque converter fails inside the transmission and they want 6000.00 to fix it, I have not had the truck 60 days

My truck has developed a radiator leak after 39930 miles. I see from reading on the Internet this is a very common problem with this year of truck. Chevrolet even has a recall to replace the radiator but says my truck is not included. The recall notice is #15829. This ends up being a very expensive repair. I have been quoted $1428.00 by a Chevrolet dealer to replace radiator.

RADIATOR IS LEAKING ON PASSENGER SIDE. CAUSES COOLING SYSTEM TO FAIL AND ALSO CAUSES COOLING FANS TO RUN EVEN AFTER THE VEHICLE IS TURNED OFF.

THE VEHICLES AFM SYSTEM HAS BENT A PUSHROD IN MY TRUCK. THERE ARE NUMEROUS COMPLAINTS ONLINE ABOUT THIS. I AM OUT OF WARRANTY AND THERE IS NO RECALL. IS THIS BEING INVESTIGATED?

OIL COOLING LINES LEAKING WAS TOLD COULD POSSIBLY RUN OUT OF OIL

THERMOSTAT CAUSED STRESS FRACTURES IN RADIATOR. THE FIRST TIME IT HAPPENED WAS IN 2018, I HAD THE RADIATOR AND THERMOSTAT REPLACED. I NOW HAD TO REPLACE THE RADIATOR AND THERMOSTAT FOR THE SECOND TIME IN 2020.

THE CATALYTIC CONVERTERS LEAK CAUSING REDUCED POWER AND EXHAUST FUMES TO ENTER CAB. ESPECIALLY WHEN STOPPED THIS CAN CAUSE NAUSEA AND DIZZINESS.

CAM AND LIFTER ISSUES. CATALYTIC CONVERTERS ARE BAD. ONLY HAVE 65000 MILES ON IT
